Head of Engineering

About , we’re building the most impactful healthcare company on Earth. We believe access to a great doctor is a basic human right. Delays, misdiagnoses, administrative chaos, and burnout plague the system.

Our Mission

One Human, One Doctor. We build AI teammates that augment clinicians — scribes, nurses, receptionists, translators — all powered by our own world‑class models and deployed in real‑world care.

Our Traction

• 450+ organizations signed 16 months ago.

• AI agents cut admin by ~2.8 hours daily and reduce onboarding 85%.

• 5M+ clinical tasks completed to date, serving 36+ specialties.

• Raised $25M from YC, Eric Yuan, Amity, Semper Virens.

• Patented AI architecture (Med Con‑1) outperforms GPT‑4.5, Gemini, Claude on clinical reasoning tasks.

What You’ll Do

• Own end‑to‑end engineering execution for your domain, from architecture and roadmap through delivery and reliability.

• Drive step‑function latency reductions, targeting at least 50% improvements across note generation and decision‑support workflows where applicable.

• Design and operate robust observability, metrics, and model‑selection systems to ensure consistent performance at scale.

• Lead domain‑specific execution rituals including daily and weekly standups, backlog ownership in Linear, and tight cross‑functional coordination.

• Translate product goals into clear dependencies, timelines, and deliverables to keep teams unblocked and shipping.

• Operationalize continuous quality evaluation pipelines to improve accuracy, completeness, and reliability of outputs.

• Set and enforce engineering best practices across your stack, including code quality, reviews, on‑call standards, and operational rigor.

What You Must Bring

• Founder‑level ownership mindset. You operate like the business depends on your decisions and execution.

• Senior, hands‑on engineering ability. You actively design systems, write and review production code, and set the technical bar by example.

• Experience in high‑intensity environments such as YC‑backed startups, early‑stage companies, or zero‑to‑one teams where speed and judgment matter.

• Comfort with ambiguity. You turn incomplete product direction into clear technical plans and ship without heavy process.

• Bias toward leverage and simplicity. You choose durable solutions and know when to optimize versus when to ship.

• Nice‑to‑have:

- Experience with FHIR/HL7 or EHR systems.
- Background in real‑time or near‑real‑time streaming, diarization, or structured‑output pipelines.
- Experience supporting front‑end or extension‑based integrations (web, mobile, browser extension).

First‑Month Focus

• Take full ownership of the assigned engineering domain.

• Ensure end‑to‑end observability and alerting for core workflows.

• Define the domain’s key performance, reliability, and quality metrics.

• Identify and ship at least one high impact improvement.

• Establish execution cadence, priorities, and quality standards.

Who Thrives Here

• Entrepreneurial to your core:
You think in outcomes, thrive in chaos, and take ownership without limits.

• Mission‑obsessed:
You’re here to save lives, not just ship features — patients and doctors are your why.

• Impact‑driven & fast‑moving:
You sprint toward hard problems and ship with sharp judgment.

• Elite teammate:
You raise the bar through high standards, direct feedback, and craft excellence.
